DETAILED DESCRIPTION

The embodiments of the disclosure are described as below with reference to the accompanying drawings, which include various details of embodiments of the disclosure to facilitate understanding, and should be considered as merely exemplary. Therefore, those skilled in the art should realize that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the disclosure. Similarly, for clarity and conciseness, descriptions of well-known functions and structures are omitted in the following descriptions.

The technical fields related to the disclosure are briefly introduced as below:

Data processing refers to collecting, storing, retrieving, processing, converting, and transmitting data. The data processing is to extract and derive data that is valuable and meaningful for some certain people from a large amount of data that may be disordered and difficult to understand. The data processing is a basic link of system engineering and automatic control. The data processing runs through all areas of social production and social life.

Artificial intelligence (AI) is a subject that studies simulating certain thinking processes and intelligent behaviors (such as learning, reasoning, thinking, planning, etc.) of human beings by a computer, which covers hardware-level technologies and software-level technologies. AI hardware technologies generally include computer vision technology, voice recognition technology, natural language processing (NLP) technology and its learning/deep learning (DL), big data processing technology, knowledge graph technology, etc.

Autonomous driving, generally referred to as autonomous vehicle, also referred to as unmanned vehicle, computer-driven vehicle, or wheeled mobile robot, is an intelligent autonomous vehicle achieved through a computer system. The autonomous vehicle relies on and cooperates with artificial intelligence, visual computing, radar, monitoring devices, and global positioning system, such that the computer may automatically and safely operate a motor vehicle without any active operation of human beings.

Intelligent traffic generally refers to intelligent traffic system (ITS), also referred to as intelligent transportation system, means effectively integrating advanced science and technologies (information technology, computer technology, data communication technology, sensor technology, electronic control technology, automatic control theory, operations planning, artificial intelligence, etc.) in traffic transportation, service control and vehicle manufacturing, and strengthening a link among vehicles, roads and users, thereby forming a comprehensive transportation system that guarantees safety, enhances efficiency, improves environment, and saves energy.

Big data means a set of data that cannot be captured, managed, and processed by a conventional software tool within a certain time range, and means massive, high-growth rate and diversified information assets which require a new processing model to have stronger decision-making power, insight and process optimization capacities.

Intelligent search refers to a technology for retrieving information with an optimal value for users from the network resources that may be acquired based on user's requests. The intelligent search with intelligent and humanized features of information services allows the user to retrieve information by natural language, thereby acquiring a convenient and accurate search service.

In the related art, due to redundant and complicated functions, the method for map query cannot allow the user to achieve the map query conveniently or acquire useful location information intuitively. Therefore, embodiments of the disclosure provide a method and an apparatus for map query to solve the above-identified problem.

The method, the apparatus, and the electronic device will be described below with reference with the drawings.

FIG. 1 is a schematic diagram according to an embodiment of the disclosure. It is to be noted that, an executive subject of the method for map query according to this embodiment is a server. As illustrated in FIG. 1 , the method for map query includes the following:

At S101, a map query request and a current location of a terminal device are acquired.

The map query request may include a query range and a query type, etc.

For example, the map query request may include information about searching for a subway station (i.e., the query type) within a 1 kilometer (km) (i.e, the query range).

It is to be noted that, in the disclosure, the map query request may be sent in many ways.

In an example, the map query request may be sent in response to a clicking operation from a user on a query control displayed on a query interface of a terminal device, such as a mobile phone. In another example, the map query request may be sent based on voice information input by the user.

Correspondingly, the server may receive the map query request sent by the terminal device.

For example, as illustrated in FIG. 2 , an application with a map query function is installed in the terminal device. After the application is launched, the terminal device may send the map query request in response to a clicking operation on a query control 2-2 displayed on a query interface 2-1.

It is to be noted that, in the disclosure, the server may acquire the current location of the terminal device in many ways.

In an example, the current location of the terminal device may be carried in the map query request, such that the server may obtain the current location of the terminal device after receiving the map query request. In another example, the current location of the terminal device is not carried in the map query request. In this case, the server may actively acquire the current location of the terminal device after receiving the map query request.

At S102, a map area to be displayed and a query object to be highlighted in the map area are acquired based on the map query request and the current location.

After the map query request and the current location of the terminal device are acquired, the map area to be displayed may be acquired based on the map query request and the current location.

It is to be noted that, the manner of acquiring the map area to be displayed based on the map query request and the current location is not limited in the disclosure, which may be selected based on actual conditions.

In an example, the map area to be displayed may be acquired based on the obtained map query request and the obtained current location, in combination with a preset default range, such as 3 km.

In another example, the query range preset by the user may be carried in the map query request. The server may obtain the query range, such as 1 km, based on the map query request after receiving the map query request, and further acquire the map area to be displayed based on the query range.

There may be one or more query object to be highlighted in the map area. In this case, one or more query objects to be highlighted in the map area may be obtained.

The term “the query object to be highlighted” refers to that the query object needs to be displayed in a highlighting manner. The query object to be highlighted in the map area may be acquired after the map area to be displayed is acquired.

It is to be noted that, the manner of acquiring the query object to be highlighted in the map area is not limited, which may be selected based on the actual conditions.

In an example, the query object to be highlighted in the map area can be acquired based on a preset strategy. For example, after the map query request is acquired, all objects within the map area may be determined as the query objects to be highlighted in the map area by default. The term “all objects” refers to each object at a relatively fixed location, such as each subway station, each bus station, each public toilet, etc.

In another example, the query type preset by the user may be carried in the map query request, and the server may obtain the query type from the map query request after receiving the map query request, and further obtain the query object to be highlighted in the map area based on the query type. For example, the query type is subway station. In this case, after the map query request is acquired, each subway station within the map area may be determined as a query object to be highlighted in the map area.

At S103, a display icon corresponding to the query object is generated.

When there are two or more query objects to be highlighted in the map area, the generated display icons correspond to the query objects one by one respectively.

For example, for the query objects A to C, corresponding display icons 1 to 3 may be generated in sequence respectively.

At S104, a radar chart of the map area is drawn based on the current location, and a location where the query object is located is marked with the display icon.

Radar chart is a graphical method of displaying multivariate data in a form of a two-dimensional chart representing three or more quantitative variables on axes starting from the same point. The relative location and angle of the axes generally carry no information.

When there are two or more query objects to be highlighted in the map area, the location where each query object is located is marked with a corresponding display icon. For example, as illustrated in FIG. 3 , the radar chart of the map area is drawn by taking the current location 3-1 as a center, and display icons 3-2 to 3-4 are displayed on the locations where the query objects A to C are located.

With the method for map query according to embodiments of the disclosure, by obtaining the map query request and the current location of the terminal device, the map area to be displayed and the query object(s) are acquired based on the map query request and the current location, and the display icon(s) corresponding to the query object(s) is generated. The radar chart of the map area is drawn based on the current location. The location where each query object is located is marked with a corresponding display icon. Therefore, in the disclosure, by displaying the radar chart with the current location as the center, the user may achieve the map query conveniently, and at the same time, acquire useful location information intuitively, which enhances efficiency in the map query process and improves the user experience.

It is to be noted that, in the disclosure, in drawing the radar chart of the map area based on the current location and marking the location where the query object is located with the display icon, the display icon may be displayed on the radar chart in a suspension manner, i.e., the display icon is displayed in an upper layer of map data.

As a possible implementation, as illustrated in FIG. 4 , the method for map query based on the above embodiment may include the following.

At S401, the map query request and the current location of the terminal device are acquired.

At S402, the map area to be displayed and the query object to be highlighted in the map area are acquired based on the map query request and the current location.

At S403, the display icon corresponding to the query object is generated.

The blocks S401 to S403 are the same with the above blocks S101 to S103 in the above embodiment, which are not repeated here.

The block S104 in the above embodiment may include the following blocks S404 to S406.

At S404, an initial radar chart of the map area is drawn with the current location as a center.

The initial radar chart may be a chart with basic geography information, as illustrated in FIG. 5 .

At S405, a location of the query object on the map area is acquired.

When there are two or more query objects, the location of each query object is acquired. Information of each query object may be set in advance, including a unique identifier such as a name of the query object, the location, and a service type, etc. In an example, the location of the query object may be obtained based on the identifier of the query object, and the location may be determined as the location of the query object on the map area. The location of the query object refers to an absolute location (or ground truth) of the query object. The absolute location can be obtained by a global positioning system (GPS).

For example, the query object is the subway station A. The acquired location of the subway station A on the map area may be east longitude: A1° B1′ C1″, north latitude: A2° B2′ C2″.

At S406, the display icon of the query object is drawn in a suspension manner above the location of the initial radar chart to obtain the radar chart.

The “suspension manner” refers to displaying the display icons in an upper layer of the map data. For example, as illustrated in FIG. 6 , the query object is the subway station A, and the display icon is 6-1. In this example, the display icon 6-1 of the subway station A is drawn in a suspension manner such that the display icon 6-1 is above the corresponding location of the initial radar chart (that is, east longitude: A1° B1′ C1″, north latitude: A2° B2′ C2″), to obtain the radar chart. When there are two or more query objects, display icons are drawn in the suspension manner above corresponding locations of the initial radar chart to obtain the radar chart.

With the method for map query according to embodiments of the disclosure, by drawing the initial radar chart of the map area taking the current location as the center, and obtaining the location of the query object on the map area, as well as displaying the display icon of the query object above the corresponding location of the initial radar chart in the suspension manner to obtain the radar chart, the drawn radar chart may display the drawn display icon(s), thereby displaying a relative location relationship between the current location of the terminal device and each query object, which further enhances the visualization effect of a map query result and further improves the user experience.

It is to be noted that, in the disclosure, in order to perform the map query rapidly and accurately, in obtaining the map area to be displayed and the query object to be highlighted in the map area based on the map query request and the current location, the query object may be obtained through screening based on the query range.

It is to be noted that, in the disclosure, the query range may be carried in the map query request, or the query range is not carried in the map query request and the user may input the query range in many ways.

As a possible implementation, as illustrated in FIG. 7 , the query range may be input in response to a clicking operation from the user on query range selecting controls 7-2 to 7-5 displayed on the query interface 7-1. In this case, the query range is carried in the map query request.

As another possible implementation, as illustrated in FIG. 8 , the query range may be input in response to a clicking operation from the user on clicking query range selecting controls 8-2 to 8-5 displayed on a search display interface 8-1. In this case, the query range is not carried in the map query request.

Taking a case that the query range is carried in the map query request as an example, as a possible implementation, as illustrated in FIG. 9 , the method for map query based on the above embodiment may include the following.

At S901, the map query request and the current location of the terminal device are acquired.

The block S901 is the same with the block S101 in the above embodiment, which will not be repeated here.

The block S102 in the above embodiment may include the following blocks S902 and S903.

At S902, the map area is determined by taking the current location as a center and the query range as a radius.

For example, as illustrated in FIG. 10 , the current location acquired is A and the query range acquired is 1 km. In this case, a circular map area 10-1 with A as the center and 1 km as the radius is determined.

At S903, the query object is obtained by screening candidate objects within the map area based on the query request.

It is to be noted that, in the disclosure, the map query request may include the query range input by the user. The query range may be a query object type or a query object name, etc.

For example, the candidate objects within the map area are subway stations and bus stations, and the query range is the subway station. In this case, each subway station obtained by screening subway stations and bus stations included in the map area may be the query object.

At S904, the display icon corresponding to the query object is generated.

When there are two or more query objects to be highlighted in the map area, two or more display icons are generated for the query objects. In an example, the display icons of the query objects are the same. As illustrated in FIG. 11 , for the query objects A to C, display icons are 11-1 to 11-3 respectively, and the display icons 11-1 to 11-3 are the same.

In another example, the display icons of the query objects may be different from each other. As illustrated in FIG. 12 , for the query objects A to C, display icons are respectively 12-1 to 12-3, and the display icons 12-1 to 12-3 have different colors.

A color depth of a display icon may be determined based on a distance between the query object and the current location of the terminal device. In an example, the distance between the query object B and the current location of the terminal device is the smallest. Therefore, the color depth of the display icon 12-2 is deepest. The distance between the query object A and the current location of the terminal device is greater than that of the query object B. Therefore, the color depth of the display icon 12-1 is lighter than that of the display icon 12-2. The distance between the query object C and the current location of the terminal device is the largest. Therefore, the color depth of the display icon 12-3 is the lightest.

At S905, an initial radar chart of the map area is drawn by taking the current location as a center.

At S906, a location of the query object on the map area is acquired.

At S907, the display icon of the query object is drawn above corresponding locations of the initial radar chart in a suspension manner to obtain the radar chart.

The blocks S905 to S907 are the same with blocks S404 to S406 in the above embodiment, which are not repeated here.

With the method for map query according to embodiments of the disclosure, by determining the map area with the current location as the center and the query range as the radius, and by screening the candidate objects included in the map area to obtain the query object based on the query request, the query object obtained through the screening may satisfy a detailed map query requirement of the user, which further improves the user experience.

It is to be noted that, in the disclosure, in order to further satisfy the requirement of the user on rapidly searching for different types of query objects, in obtaining the query object by screening the candidate objects included in the map area based on the query request, the query object may be obtained through the screening based on the query object type input by the user.

It is to be noted that, in the disclosure, the query object type may be carried in the map query request, or it is possible the query object type is not carried in the map query request, and the user may input the query object type in many ways.

As a possible implementation, as illustrated in FIG. 13 , the query object type may be input in response to a clicking operation from the user on query object type selecting controls 13-2 to 13-5 displayed on the query interface 13-1. In this case, the query object type is carried in the map query request.

As another possible implementation, as illustrated in FIG. 14 , the query object type may be input in response to a clicking operation from the user on query object type selecting controls 14-2 to 14-5 displayed on the search display interface 14-1. In this case, the query object type is not carried in the map query request.

Taking the case that the query object type is carried in the map query request as an example, as a possible implementation, as illustrated in FIG. 15 , on the basis of the above embodiment, obtaining the query object by screening the candidate objects included in the map area based on the query request at the block S903 includes the following.

At S1501, the query object type is acquired.

The query object type may be a preset type corresponding to an object that is able to be presented on the initial radar chart. For example, the query object type may be restaurant, subway station, bus station, or supermarket, etc.

It is to be noted that, in the disclosure, the number of query object types carried in one map query request is not limited. As an example, the user may perform the map query for one query object type. As another example, the user may perform the map query for three query object types at the same time.

At S1502, the query object is obtained by screening the candidate objects included in the map area based on the query request type.

It is possible that two or more query objects are obtained by screening the candidate objects within the map area based on the query request type. Further, it is possible that there are query objects obtained based on two or more query request types. In order to distinguish different types of query objects on the radar chart, the display icons may be displayed in different display styles based on the query object types.

For example, as illustrated in FIG. 16 , for the query objects A to C, the display icons are respectively 16-1 to 16-3, and the display icons 16-1 to 16-3 have different styles. For example, the query object is the subway station A and the display style of the display icon 16-1 is a subway station identifier; the query object B is the restaurant and the display style of the display icon 16-2 is a restaurant identifier; the query object C is supermarket and the display style of the display icon 16-3 is a supermarket identifier.

With the method for map query according to embodiments of the disclosure, by setting different display styles of display icons for different types of query objects, different types of query objects displayed on the radar chart may be distinguished by displaying different display styles of display icons, which further improves the user experience.

It is to be noted that, in the disclosure, the server may send detailed information of a target query object to the terminal device in response to a request for displaying detailed information of the target query object, such that the terminal device displays the detailed information.

As a possible implementation, as illustrated in FIG. 17 , the method for map query according to the disclosure, on the basis of the above embodiment, includes the following.

At S1701, a request for displaying detailed information of a target query object is acquired.

It is to be noted that, in the disclosure, the request for displaying detailed information of a target query object may be sent in many ways.

In an example, the request for displaying detailed information of a target query object may be sent in response to a clicking operation on a display icon on the search display interface of the terminal device such as a mobile phone.

Correspondingly, the server may receive the request for displaying detailed information of a target query object sent by the terminal device and designated by the user.

At S1702, detailed information of the target query object is generated based on the request, and detailed information is sent to the terminal device. The detailed information at least includes a name of the target query object and a target location of the target query object.

As a possible implementation, as illustrated in FIG. 18 , on the basis of the above embodiment, generating the detailed information of the target query object and sending the detailed information to the terminal device at the block S1702 includes the following.

At S1801, a name and a target location of the target query object are acquired based on the request.

For example, after the request for displaying detailed information of a subway station A is acquired, the name of the subway station A and the target location A may be acquired.

At S1802, relative location information between the terminal device and the target query object is acquired based on the current location and the target location.

The current location and the target location are both absolute geographic coordinates. The absolute geographic coordinates refer to the geographic coordinates in the real world, which can be obtained by a GPS. In this case, relative location information between the terminal device and the target query object may be acquired.

At S1803, the name and the relative location information are determined as the detailed information of the target query object.

With the method for map query according to embodiments of the disclosure, the name and the target location of the target query object may be acquired based on the request, and the relative location information between the terminal device and the target query object may be acquired based on the current location and the target location. The name and the relative location information may be determined as detailed information of the target query object. Therefore, the user may acquire the detailed information of any target query object from the query result, which further improves the user experience.

It is to be noted that, in actual applications, since the current location of the terminal device and the query requirement from the user are dynamic, the radar chart may be updated in response to detecting an update event of the radar chart in the disclosure.

In an example, an updated radar chart may be generated and sent to the terminal device in response to the update event of the radar chart such that the terminal device displays the updated radar chart.

The update event of the radar chart includes obtaining a request for modifying a query condition or a display time of the radar chart reaching a preset time threshold. The preset time threshold may be set based on actual situations, such as 2 seconds (s), 5 s, etc.

With the method for map query according to embodiments of the disclosure, by generating and sending the updated radar chart to the terminal device in response to the update event of the radar chart, the displayed radar chart may satisfy actual requirements, which improves the efficiency and reliability in the map query process.

FIG. 19 is a diagram according to an embodiment of the disclosure. It is to be noted that, the executive subject of the method for map query in this embodiment is the terminal device. As illustrated in FIG. 19 , the method for map query according to embodiments includes the following.

At S1901, a map query request is sent to a server.

It is be noted that, in the disclosure, the map query request may be sent in many ways.

In an example, the map query request may be sent in response to a clicking operation from the user on a query interface of the terminal device such as a mobile phone. In another example, the map query request may be sent in response to voice information input by the user.

Correspondingly, the server may receive the map query request sent by the terminal device.

At S1902, a radar chart sent by the server is received, and the radar chart is displayed.

In an example, the terminal device may receive the drawn radar chart sent by the server, and call a search display page to load the radar chart on the search display page.

With the method for map query according to embodiments of the disclosure, the map query request may be sent to the server and the radar chart sent by the server may be received and displayed. Therefore, in the disclosure, by displaying the radar chart with the current location as a center, the user may perform the map query conveniently, and at the same time acquire useful location information intuitively, which enhances the efficiency in the map query process and improves the user experience.

It is to be noted that, in the disclosure, the terminal device may send a request for displaying detailed information of a target query object to the server, to acquire and display the detailed information of the target query object.

As a possible implementation, as illustrated in FIG. 20 , the method for map query according to the disclosure, based on the above embodiment, includes the following.

At S2001, a request for displaying detailed information of a target query object is sent.

It is to be noted that, in the disclosure, the request for displaying detailed information of a target query object may be sent in many ways.

In an example, the request for displaying detailed information of the target query object is sent in response to a clicking operation from the user on a display icon displayed on the search display interface of the terminal device such as a mobile phone.

Correspondingly, the terminal device may send the request for displaying detailed information of the target query object to the server in response to monitoring a corresponding operation from the user.

At S2002, detailed information of the target query object sent by the server is received and displayed. The detailed information at least includes a name of the target query object and a target location of the target query object.

It is to be noted that, in order to further improve the user experience, a display style can be preset for displaying the target location of the target query object. In an example, the target location may be not displayed in a format of {latitude, longitude}, but in a format of {number, road, district, city}.

As a possible implementation, as illustrated in FIG. 21 , based on the above embodiment, displaying the detailed information at the block S2002 includes the following.

At S2101, a display pop-up window corresponding to the detailed information is generated.

Configurations, such as the style and the size, of the display pop-up window are not limited in the disclosure, which may be set based on actual situations.

At S2102, a location where the target query object is located on the radar chart is acquired, and a display area of the display pop-up window is determined based on the location.

At S2103, the display pop-up window having the detailed information is displayed in the display area.

For example, as illustrated in FIG. 22 , the target query object is the subway station A. In this case, the display pop-up window 22-1 having the detailed information is displayed within the display area.

It is to be noted that, in actual applications, since the specific query requirement from the user is dynamic, a request for modifying a query condition can be sent to the server to instruct the server to update the radar chart in the disclosure.

As a possible implementation, as illustrated in FIG. 23 , based on the above embodiment, the method includes the following.

At S2301, a request for modifying a query condition is sent to the server, to instruct the server to update the radar chart.

For example, the terminal device may send the request for modifying the query condition, such as a request for modifying the query range, to the server, such that the server updates the radar chart based on the modified query range.

At S2302, an updated radar chart is received and displayed.

With the method for map query according to embodiments of the disclosure, by sending the request for modifying a query condition to the server to instruct the server to update the radar chart, and by receiving and displaying the updated radar chart, the displayed radar chart may satisfy actual requirements, which improves the efficiency and reliability in the map query process.

Taking a query process of relevant functions of remote dictionary server (Redis) geography (GEO) as an example, the whole process of the method for map query according to the disclosure is illustrated.

The map query request may be sent by the terminal device. In this case, the terminal device may acquire and send the current location to the server once obtaining authorization from the user. The current location including latitude and longitude information may be taken as parameters to request a cloud data interface from the server.

Further, after the server receives the current location, the server may acquire the query type and the query range and call a get Point-of-Interest list (getPoiList) method to obtain the query object. For example, by transmitting the getPoiList (City: SUBWAY, “longitude information”, “latitude information”, “2 km”), the gepradius and geopos methods provided by the Redis can be called, and the information with a specific data format is obtained through splicing based on the parameter conversion and calling and sent to the terminal device.

The georadius refers to a method for finding an element within a certain radius with a location at a given longitude and a given latitude as a center. The geopos refers to a method for acquiring coordinates of a geographic location.

The terminal device may display radar chart and mark the query object(s).

Details of a target query object can be obtained by clicking a display icon on the radar chart by the user. The details at least include the name of the target query object and the target location of the target query object.

It is be noted that, the information such as the names and the locations of the query objects is entered in advance, but effective location information of the terminal device cannot be entered in advance. In this case, the target location may be acquired by means of the geodist method of the Redis GEO based on the longitude and latitude information of the current location. For example, a temporary location of the terminal device may be created based on an identity document (ID) of the user and time. Further, the created temporary location may be deleted after the target location is obtained. The details is sent to the terminal device, such that the user may acquire the detailed information of the target query object through the terminal device.

Further, since the location of the terminal device is constantly changing, the radar chart may be constantly refreshed to ensure the accuracy. In an example, a timer may be equipped on the terminal device to request server data periodically every 2, 3, 4 or 5 seconds to render the map, such that the updated radar chart is generated.

With the method for map query according to embodiments of the disclosure, a method for acquiring information of the query object rapidly, accurately, and intuitively may be provided to the user, and the modification of the query condition may be achieved based on easy operations, thereby enhancing the efficiency in the map query process and improving the user experience.
